In a letter sent home to parents, school principal Julio Duarte wrote: "As educators, we are entrusted to protect and educate all of our students and know there are certain boundaries that can never be crossed.

"Also, we will not tolerate any behaviour that compromises the safety or well-being of our students.

"I hope you will not let the misconduct of this one individual cast a shadow over all of our staff members who demonstrate their commitment to our students every day.”
